These two applications (Macro Toolworks 8.x and SnagIt 11.x by Techsmith) used to work fine together. Then one day, that stopped. My guess would be a windows update, since at the time I hadn't changed or updated either one.

I re-installed SnagIt 11, no help. I upgraded Macrol Toolworks to the latest, no help.

Problem behavior:
SnagIt is behaving really slow when MTW is running. The problem is made really obvious if I simply right-click SnagIt in the system tray. It takes 5-6 seconds before the context menu shows. If I then exit Macro Toolworks and try it again, it takes less than 1 second. This behavior is repeatable.
